Abstract

A pressurised air compressor unit for the power supply of a pneumatic level adjusting system of a motor vehicle comprises an electric motor and an air dryer together with a pressure compressor and is arranged in a tank held in the vehicle body and surrounded by sound-reducing layers (6, 8). The compressor unit in a dish shaped tank (5) is covered over its surface by a heat accumulator (9) which, with the heat accumulator (9) embedded in the one sound-reducing layer, encloses the unit all round. In this way a compact device is created for cooling of the compressor unit with a simultaneously sound-insulating arrangement. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Aus der DE-A 28 04 653 ist eine Vorrichtung zur Kühlung und Geräuschdämpfung von Kompressoren und Vakuumpumpen für eine stationäre Anlage bekannt, bei der die Aggregate in einem mit Wasser gefüllten geschlossenen Behälter angeordnet sind, der einen äußeren Kühler aufweist. Eine Schalldämmung erfolgt durch eine vollständige Ummantelung des im Abstand zu den Aggregaten angeordneten Behälters mit einer schallmindernden Schicht. Eine derartige Vorrichtung dämmt nicht ausreichend die Geräusche und ist zur Anwendung in einem Kraftfahrzeug aufgrund der möglichen Bewegung der Flüssigkeit im Behälter sowie der äußeren Kühlung aus Platzgründen und wegen hoher Kosten nicht verwendbar.From DE-A 28 04 653 a device for cooling and noise reduction of compressors and vacuum pumps for a stationary system is known, in which the units are arranged in a closed container filled with water, which has an external cooler. Sound insulation is achieved by completely encasing the container, which is arranged at a distance from the units, with a sound-reducing layer. Such a device does not adequately insulate the noise and cannot be used in a motor vehicle due to the possible movement of the liquid in the container and the external cooling for reasons of space and because of the high cost.

Aufgabe der Erfindung ist es, eine Vorrichtung zur Kühlung und Geräuschdämmung für eine Kompressoreinheit in einem Kraftfahrzeug zu schaffen, die eine Überlastung der Aggregate durch Aufwärmung vermeidet und gleichzeitig eine verbesserte Geräuschdämmung bewirkt.The object of the invention is to provide a device for cooling and noise insulation for a compressor unit in a motor vehicle, which avoids overloading the units by warming up and at the same time brings about improved noise insulation.

Die Aufgabe der Erfindung wird durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.The object of the invention is solved by the features of claim 1. The dependent claims contain further advantageous features.

Mit einem Druckluftkompressor für eine Niveauregelanlage eines Kraftfahrzeugs soll ein geschwindigkeitsabhängiges Absenken des Fahrzeugs sowie ein Anheben auf ein Normalniveau bei geringen Geschwindigkeiten auch im Stop-and-Go-Verkehr möglich sein, ohne daß der Kompressor wegen Überlastung abgeschaltet wird, was einen Ausfall der Niveauregelanlage zur Folge hat.With a compressed air compressor for a level control system of a motor vehicle, a speed-dependent lowering of the vehicle and a raising to a normal level at low speeds should also be possible in stop-and-go traffic without the compressor being switched off due to overload, which leads to a failure of the level control system Consequence.

Durch einen Wärmespeicher, der die aus einem Druckkompressor, einem Motor und einem Lufttrockner bestehende Baueinheit großflächig, insbesondere im Bereich der Funktionseinheiten, flächenhaft abdeckt, wird ein Wärmeübergang von der Einheit zu einer Aufbauwand des Fahrzeugs erzielt, an der die Einheit anliegend montiert ist. Durch die hohe Wärmespeicherfähigkeit der aus Wasser und Frostschutzmittel bestehenden Flüssigkeit im Speicher fließt in der Kompressoreinheit die entstehende Wärme durch das Temperaturgefälle zwischen der Baueinheit und dem Wärmespeicher ab. Hierbei verzögert sich die Aufwärmung des gesamten Systems und es sind deutlich mehr Schaltzyklen möglich.A heat accumulator, which covers the unit consisting of a pressure compressor, a motor and an air dryer over a large area, in particular in the area of the functional units, achieves heat transfer from the unit to a body wall of the vehicle, on which the unit is mounted in close contact. Due to the high heat storage capacity of the liquid consisting of water and antifreeze in the storage unit, the heat generated in the compressor unit flows away due to the temperature gradient between the unit and the heat storage unit. The warming up of the entire system is delayed and significantly more switching cycles are possible.

Die Anordnung der Baueinheit in schallmindernden Halbschalen, welche diese Einheit umschließen, ist wärmetechnisch an und für sich relativ ungünstig, was durch den Wärmespeicher ausgeglichen wird, der flächenhaft mit der Aufbauwand in Kontakt steht und in der einen Halbschale eingebettet ist und mit dieser Halbschale zusätzlich schallmindernd wirkt.The arrangement of the structural unit in sound-reducing half-shells, which enclose this unit, is inherently relatively unfavorable from a thermal point of view, which is compensated for by the heat accumulator, which is in extensive contact with the structural wall and is embedded in a half-shell and is additionally sound-reducing with this half-shell works.

Durch die Anordnung der beiden Halbschalen und des Wärmespeichers ist die Baueinheit rundum ganzflächig umschlossen, was einer Kapselung entspricht, die schallmindernd wirkt und der Wärmeabfuhr dient.Due to the arrangement of the two half-shells and the heat accumulator, the entire unit is enclosed all around, which corresponds to an encapsulation that has a sound-reducing effect and serves to dissipate heat.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.

Die Vorrichtung ist in einem Kraftfahrzeug eingebaut und umfaßt im wesentlichen eine Kompressoreinheit 1, bestehend aus einem Druckluftkompressor 2 für eine Energieversorgung einer pneumatischen Niveauregelanlage, die nicht näher gezeigt ist. Mit dem Kompressor 2 ist ein Elektromotor 3 und ein Lufttrockner 4 verbunden.The device is installed in a motor vehicle and essentially comprises a compressor unit 1, consisting of a compressed air compressor 2 for supplying energy to a pneumatic level control system, which is not shown in detail. An electric motor 3 and an air dryer 4 are connected to the compressor 2.

Diese Einheit 1 ist in einem schalenförmigen Behältnis 5 angeordnet und über ein schallminderndes unteres Element 6 zum Boden 7 des Behältnisses 5 hin elastisch abgestützt. Das Element 6 ist als Halbschale ausgeführt und umgibt die Einheit bis zu einer Ebene X-X allseitig. Diese Ebene X-X verläuft etwa in einer Mittelquerebene der Aggregate 3 und 4. Ein weiteres schallminderndes oberes und als Halbschale ausgeführtes Element 8 schließt sich lückenlos an das untere Halbschalen-Element 6 an und umgibt alle Aggregate 2, 3 und 4.This unit 1 is arranged in a bowl-shaped container 5 and is elastically supported towards the bottom 7 of the container 5 via a sound-reducing lower element 6. The element 6 is designed as a half-shell and surrounds the unit on all sides up to a plane X-X. This plane X-X runs approximately in a central transverse plane of the aggregates 3 and 4. Another sound-reducing upper element 8, which is designed as a half-shell, connects seamlessly to the lower half-shell element 6 and surrounds all the aggregates 2, 3 and 4.

Die Kompressoreinheit 1 ist mit ihrer im Behältnis 5 freiliegenden Seite von einem Wärmespeicher 9 abgedeckt, der in einem Ausschnitt 10 des oberen Elements 8 eingebettet gehalten ist.The compressor unit 1 is covered with its side exposed in the container 5 by a heat accumulator 9, which is held embedded in a cutout 10 of the upper element 8.

Die Halbschalen der schallmindernden Elemente 6 und 8 sowie der Wärmespeicher sind den Konturen der Gehäuse der Pumpe 2, des Motors 3 und des Lufttrockners 4 weitestgehend angepasst, so daß insbesondere der Wärmespeicher 9 einen unmittelbaren flächigen Kontakt mit diesen Aggregaten aufweist und ein optimaler Wärmeübergang gewährleistet ist.The half-shells of the sound-reducing elements 6 and 8 and the heat accumulator are largely adapted to the contours of the housing of the pump 2, the motor 3 and the air dryer 4, so that in particular the heat accumulator 9 has direct surface contact with these units and an optimal heat transfer is ensured .

Das schalenförmige Behältnis 5 wird mit einer Aufbauwand 10 des Fahrzeugs verbunden, an die eine Wand 11 des Wärmespeichers 9 anliegend ist, wodurch zusätzlich Wärme abgeführt wird. Diese Wand 11 ist gegenüberstehend einer weiteren Wand 12 vorgesehen, welche mit den Gehäusen der Aggregate 2, 3 und 4 in Kontakt steht. Wie Fig. 4 näher zeigt, ist auch die Halbschale 8 dem Verlauf der Aufbauwand 10 angepasst.The bowl-shaped container 5 is connected to a body wall 10 of the vehicle, against which a wall 11 of the heat accumulator 9 is in contact, whereby additional heat is dissipated. This wall 11 is provided opposite a further wall 12 which is in contact with the housings of the units 2, 3 and 4. As FIG. 4 shows in more detail, the half-shell 8 is also adapted to the shape of the structural wall 10.

Der Wärmespeicher 9 besteht vorzugsweise aus einem dünnwandigen Kunststoffbehälter, dessen Wände flexibel ausgeführt sind. Die den Aggregaten zugerichtete Wand 12 ist dicker ausgeführt als die gegenüberliegende Wand 11, um durch Reibung der Aggregate verursachten Abnutzungen entgegenzuwirken. Der Wärmespeicher 9 ist mit einer Flüssigkeit, bestehend aus einem Gemisch aus Wasser und Frostschutzmittel gefüllt.The heat accumulator 9 preferably consists of a thin-walled plastic container, the walls of which are flexible. The wall 12 facing the units is made thicker than the opposite wall 11 in order to be caused by friction of the units Counteract wear and tear. The heat accumulator 9 is filled with a liquid consisting of a mixture of water and antifreeze.

Die Halbschalen 6 und 8 umschließen die Einheit 1 rundum stirnseitig sowie oben- und unterseitig im Behältnis 5, wobei der Wärmespeicher 9 neben seiner Funktion als Wärmeabfuhrelement zusätzlich auch schallmindernd wirkt und hierzu paßgenau in eine Öffnung 13 der oberen Halbschale 8 eingefügt ist, wie Fig. 2 näher zeigt. Desweiteren zeigt Fig. 2 auch, daß der Wärmespeicher 9 hauptsächlich den die meiste Wärme verursachenden E-Motor 3 und den Lufttrockner 4 überdeckt, welche wesentliche Wärmequellen darstellt, so daß ein Wärmeübergang zum Druckluftkompressor 2 unterbunden wird. Eine weitere Erstreckung z.B. über die gesamte Einheit 1 ist ebenfalls möglich, zumal eine Schallminderung auch durch den Wärmespeicher erzielt wird.The half-shells 6 and 8 enclose the unit 1 all around on the front and top and bottom in the container 5, the heat accumulator 9 also having a sound-reducing effect in addition to its function as a heat-dissipating element, and for this purpose it is inserted in an opening 13 in the upper half-shell 8, as shown in FIG. 2 shows in more detail. Furthermore, Fig. 2 also shows that the heat accumulator 9 mainly covers the most heat-producing electric motor 3 and the air dryer 4, which is an essential source of heat, so that heat transfer to the compressed air compressor 2 is prevented. A further extension e.g. Over the entire unit 1 is also possible, especially since a sound reduction is also achieved by the heat accumulator.
